Kalwall translucent cladding lights up education buildings

Refurbishment at Featherstone High School demonstrates how Kalwall new façades provided diffused and healthy daylight into the interior.

Featherstone High School in Southall, Middlesex

The original 1958 concrete framed building was failing due to decay and ingress of water and needed structural stabilisation.

DSP Architecture appointed to repair and encapsulate the frame, resulting in a stunning transformation into a very modern teaching block that complemented the other new school buildings. The build was completed in two phases over the course of a year while the school continued to operate. The school continued to function while the work was completed with minimum disruption to staff and students and minimal use of temporary classrooms during the works, saving time and money.

Old concrete spandrel panels were removed and the concrete structure was repaired. Over-cladding with Kalwall panels supported on a new steel frame which was added to extend the floor space.

Kalwall translucent cladding role in renovation

The two fully replaced elevations are a perfect example of how Kalwall can be used for the refurbishment of old and failing cladding and for aged buildings. The new façades allow floor to ceiling diffused and healthy daylight to flood the interior while providing privacy for students and removing any distractions. An integrated row of clerestory windows provides ventilation and limited views to the outside. Studies show there is a high correlation between daylighting and increased human comfort. Kalwall eliminates all shadows and glare and the stark contrasts of light and shade which not only reduces eye fatigue but also enhances concentration.

The system also enhances simplicity by doing away with the need for blinds, curtains or solar control.  Even on cloudy days, the interior is flooded with natural daylight, which means less artificial lighting and, because Kalwall is highly insulating, energy costs are reduced. The standard Kalwall 70mm thick panel offers insulation up to 0.28W/m2K – equivalent to a cavity filled solid wall.

Geraldine Walder project architect at DSP: “The client specifically requested Kalwall for this project after seeing how well it worked on our previous project for the adjoining 6th form building. The advantage of it being fabricated off-site meant disruption and time on-site were minimised while the combination of high insulation, natural daylight and ventilation means reduced energy costs”.
